On that note, I use a common household fork, 1 prong bent to act as a spring puller, works great, fits in hand great too been using this since the 80s

I learned the penny trick (actually read about using washers, but had a bowl of pennys on the bench) for removing GL1000 and CB750F kickstand and center stand springs. Much heavier than the RD400 springs!

Crank is back, looking great. I hope to get started on reassembly early next week. Gave up on the enter stand pivot. After four days penetrant soak and heating it refuses to budge, so it will just get cleaned and painted as a unit with the frame. Still rolling the tank around with Evaporust in it. Should be pouring that out, rinsing, drying, and fogging this evening.

After about four days soaking with a gallon of Evaporust, I drained the gas tank, rinsed, and dried it followed by spraying the inside with fogging oil. Now the Evaporust is in a plastic tub with the rear sprocket, washers, etc. soaking in it.

No photos today, but the RD400 case mating surfaces are cleaned up (about six hour's work) and the transmission installed and tested that it shifts (one hour's work). Tomorrow the crank goes in!

Case mated and clutch/right side transmission assembled. Almost ready to install the right side cover but I want to test the oil pump first.

Question - I have a new right side gasket for it. Do folks normally use any gasket cement on them? The old one was stuck to the cover really well with something that dried hard and didn't seem to give way to acetone. I personally like Indian Head Gasket Shellac. Old school, but it stays tacky for quite a while and dissolves in acetone for removal. I just use it to hold the gasket in place (in this case I plan to use it on the cover.) Is this Ok?

Not everyone checks the Restoration Section, if you don't get an answer to your query try asking the question in the Tech Help

Case mated. Oil pump working great. Did some cleaning on the frame and parts while waiting for wrist pins and clips. Took the frame to a car wash, sprayed it with Gunk, then oven cleaner, then hit it with the soap wand and rinse wand. It shows evidence of having paint over rust (not real bad, but that's never good) as well as paint over the headstock label and rear Brake Fluid label (probably others, but that's all I can find). Thumbnail brought them both semi-legible. Did a little abrasive wheel work and more scrubbing. Primed a few spots  on the frame, and primed and painted (first coat) the footpeg mount, pillion peg mounts, and swing arm. I'm sure the swingarm welds are good, but what did they use, a Harbor Freight AC flux core MIG? That's much more weld spatter than I've ever seen on factory welds, even Hondas.

No pictures today (well, I took them, but forgot to bring the camera up from the garage). All buttoned up, rotor and stator mounted, and timing set (figured it would be easier with the engine on the bench). Plugged intake and put it in the big plastic storage box. I need to do some lathe bit grinding and cut a flange on the lathe, so best to have it protected from that. After finishing with the lathe, I might get to de-rust the remainder of the frame and prime it. Then, ,all get stored away as we are having work done on our house that will require me to consolidate two GoldWings and the RD400 parts into the front half of the garage so that sheetrock can be ripped out over the garage door.

I had started cleaning off the spots where I could see that the frame had rust painted over (a no-no for Navy guys). Got about half of it done and the wife started doing dusty things so I put it up. She worked today, so I finished putting etching primer on the spots I had found before and cleaned up the rest of it and applied etching primer to the whole frame. About an hour later I was able to get a coat of Rustoleum Appliance Epoxy Black to the part of it that I could hit with it upside-down. Tomorrow, if the weather is still good, I will flip it over and finish the black on it, then hang it from the garage ceiling until ready for assembly.

I try to do at least a little something on it every day, even though most is now put up in preparation (soon, we hope!) for house remodel. Yesterday I cleaned, tested, and painted the clocks and their frame. Today I assembled the dash and tested all lamps and the circuit that switched on-and-off from the speedometer to give input to the signal cancel unit. Full speed fast (in reverse) on my VSR battery powered drill is ~ 30 MPH and 6 K RPM.

Finished removing the paint from the tank. Bondo on the small dents and the one big rough spot left on the front after using the stud welder on it. The a lot of sanding, and more Bondo, more sanding, Bondo Glazing and spot putty, more sanding. Primed the bottom (tunnel) with etching primer, then the top. Noticed some rough spots on the top, so built up about four layers of filler primer (the red). I'll let that cure overnight and hit it tomorrow with sanding again. If good then, a good etching primer layer to seal everything so the lacquer will not react with any small bit I may have left. Considering leaving the tunnel with just the etching primer and then clear over the whole thing when it comes time.
